i 'Myinvention relates-tonloose leaf binders,

and litisni'y obj'ec'tto .providesuch a binderl inwhich the Asplit rings 'are locked together `'without the use `of aspringelement.

. More particularly,fm'yinvention embodies 'i Q'Ai'fiirtherobj ect -of my inventionisto provide such alstructurefwhich is a?. very simv,ple,f durable y.and 'inexpensive construction. Another object-,fof the' present finv'ention is to provide Vsuch 'a`binder in `which VtheV rings are locked `in closedfposition by the engagement of the crank rod vwith ,one of its Ycoacting members', in such a waythat the coacting` throw of thecraink rod has moved past dead center, relative'to saidmember and v'the crank handleV of the crankrod has'V ensaid'past-deadcenter position.

Al/Vith these and other objects in View, my invention consists in the construction, arrangement and combinationof the various parts of my device, whereby the objects conn templated are attained, as hereinafter more fully set forth, pointed -out in my claims,

and illustrated in the accompanying draw-l ings, in which:

Fig. 1 is a plan view of the binder in closed position, a portion of a book back being shown attached thereto.

Fig. 2 is a similar view of the binder in open position. y .l

Fig. 3 is an end view of the binder itself.

Fig. 6 is a transverse sectional View, taken on the line 6 6 of Fig. 2.

Fig. 7 is a transverse sectional view, taken on the line 7-7 of Fig. 2.

Fig.8 is a planeview of a portion of the binder illustrating a modified form of the means for connecting the rings to the binder.

Fig. 9 is a transverse sectional view of the same, taken on the line 9 9 of Fig. 8.

. I have used the reference charactervl() to indicate generally the leather, composition .orfabric 'covering of a loosepleaf book.v The binder'for;thefbook'comprises appair of angle-shaped; ribs', 11 fa'nd*l2, which are hinged together' ji ii`eafns'jy "of hinges, 413, and secured toj-the v covering, 10, as ,`by, ;ine`a'ns of lacing `jorfclips, 14,' eXtending' through openings, 15, .-'inthewb'inde dfthroughfthe covering.

@ The'l leafre ceivifng yring elements, 16 and 417', are! secured 'to the ribs, 111 and 12',`respec tively,` by;ftlilreading.`into any of' `several ``tapped openings, 18, in the respective ribs. vThusth`e""ri`n, g`js may beadjusted longitudinallyfoft-he binder. to K loose leaves.

,It varying -sizs of Vl.In"niost'types of binders afspring is used 5to maintain'fthetwo halves lofthe binder in `position, kin lwhich ,the Arings will, befclosed aand.lockedl against each. other. I, provide j means eliminating the necessity, .of springs and inwhich 'it: isnotnecessary. to grasp -the rings themselves .to open them; This r' com-prisesa crankf'rod, 19e journale'd in lips, projecting: 'ul'aw'v'ardlyfromy the rib, ,1-1, and 'h'a'vin'g the crank throws',1f21 and22. gaged one of the ribs of the binder toprevent .furthermovement vof the throw beyond The: crank throws:21 landY` .,22, `extend apfrom the axis'f'of thehcrank rod.i An arm, 23, is secured to the rib, 12, and-extends over the throw, 22. Arms, 24, are secured to the rib, 12, and extend under the throws, 21,

and when the binder is inV closed position, are i passed slightly beyond dead center relative to the elements, 24, and will engage said elements with suiiicient pressure to prevent the Fig. 4 is a transverse sectional view, taken crank rod accidentally rotating to position to allow the binder to open. l

It will be understood that the resiliency of the crank rod itself will allow thethrows,

range of movement of the V'crankarm toward the open position shown in Fig. 2 by accommodating the flange of the rib, 11.

. Figs. 3, 4 and 5 show the variousportions of the crank arm in the Vclosed position illus' trated in Fig. 1. Fig. 4 illustrates how the throw, Y 22,has been rotated to position to to i prokiinately iii .thea saine. direction radially loo ' out a flange, andis provided with a series of slots, 12", in each of its edges.' The ring, 12, has a U-shaped port-ion,'12d, thev arms of which are received in opposite ones of the slots, 1 2", and which embraces the rib, as shown` in Fig. 9.

A locking clip, 12e, coacts with slots, 12f, in the portion, 12d, to maintain the ring Vinv attachment with the rib'.`

Some changes may be made in the construction and arrangement of the Vparts'oi my invention without departing from the real spirit `and purpose of my invention, and it is my intention t0 cover by my claims, any modified forms ot'structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as'my invention: Y A1. In a vloose leaf binder, a .pair of ribs hinged together, a crank rod journaled over one of the ribs, and having throws, and members secured to the other rib, extending above and below said throws.

2` ,In a. loose leaf binder, a pair of ribs hinged together, avcrank rod journaled on one" rib, a member secured to the otherz rib and extending under a throw of the crank rod, said `throw being adapted to force the said member against the rib under the crank rod, and a crank handle adapted to engage one of the ribs, in position allowing said throw to pass dead-center relative to its coacting member and to thereby lock the ribs against' liinginginovement. i

'3. In a loose leaf binder, a pair of' ribs hinged together, a crank rod journaled on one rib, a member secured .to the other rib and extending under a throw of the crank rod, said throw being adapted to force the said member against the rib under the crank rod, a crank handle adapted to engage one of the ribs in' position lallowing said'throw ,to pass dead center relative to its coacting member and to thereby lock the ribs against hinging movement, and means coacting with vthe crank rod tov cause the ribs Ato hinge away from said locked position.

ifi- In a loose leaf binder, a pair of ribs hingedtogether, lips projecting from one of said ribs, a crank rod journaled in said lips, and members secured to the other rib,

projecting above and below throws of said,

crank rod. l
